We all want to be individuals. We like knowing that there's only one "me" in this world. There's nobody else with the same exact compilation of personality, looks, talents, etc. We are one of a kind and special. And we like it that way.
The funny thing is, we also really like knowing that someone else feels the same way we do, or has experienced what we have. Knowing that someone else can relate to what we're going through helps us feel like we're not alone, that we're not unique in our struggles.
We want to be special and unique until we find that we can't do everything on our own. Then it's really reassuring to find others who are just like us. And in the end, that seeming contradiction is part of what makes us human. So different, but so alike, all at the same time.
